Fault Analysis and Troubleshooting of Flat Plate Magnetic Separator

Magnetic separator is an important separation equipment, and its main function is to use magnetic force to separate materials with magnetic differences. In mining, magnetic separator can separate magnetic minerals and improve the quality of ore; in the field of resource recovery, it can recover valuable magnetic materials from waste; in coal, non-metallic minerals, building materials and other industries, magnetic separator is used to remove ferromagnetic impurities in raw materials; at the same time, in the food and chemical industries, magnetic separator is also used to ensure the purity of products. In short, magnetic separator plays an important role in many fields. The appropriate flat plate magnetic separator model and parameters should be selected according to the different materials, and regular maintenance should be carried out to ensure the normal operation and separation effect of the equipment.

A. Fault analysis of flat plate magnetic separator

When a flat plate magnetic separator fails, the cause of the failure should be analyzed in time and targeted measures should be taken to solve the problem. At the same time, regular maintenance of the equipment can reduce the probability of failure and improve the operating efficiency of the equipment.

When analyzing the failure of the flat magnetic separator, we need to start from the following aspects:

1. Abnormal noise of the equipment: If the flat magnetic separator has abnormal noise, it may be caused by bearing damage, gear wear or loose chain. At this time, we need to check and replace the relevant parts.

2. Poor magnetic separation effect: If the magnetic separation effect of the flat magnetic separator is not good, it may be caused by insufficient magnetic field strength, improper pole distance adjustment or uneven material flow. At this time, we need to adjust and optimize the magnetic field strength, pole distance and material flow.

3. Transmission system failure: If the transmission system of the flat magnetic separator fails, it may be caused by motor damage, reducer failure or chain breakage. At this time, we need to check and repair the relevant parts.

4. Support system failure: If the support system of the flat magnetic separator fails, it may be caused by bracket damage, support wheel detachment or bearing damage. At this time, we need to check and repair the relevant parts.

When analyzing the failure of the flat magnetic separator, we need to start from multiple aspects, check the problems one by one, and take corresponding measures for repair and replacement. At the same time, in order to reduce the occurrence of failures, we also need to regularly inspect and maintain the equipment.

B. How to solve the failure of the flat magnetic separator?

The flat magnetic separator may fail during use. For different failures, corresponding solutions should be taken:

1. The equipment cannot start: check whether the power connection is normal, whether the switch is damaged, and promptly troubleshoot or replace damaged parts.

2. Reduced magnetic field strength: Check whether the magnetic system is damaged or aging, and adjust the magnetic field strength or replace the magnetic system in time.

3. Material blockage: Check whether the feed port and the discharge port are blocked by materials, clean up the blockage, and ensure smooth material flow.

4. Poor sorting effect: Check whether the parameters such as magnetic field strength, material particle size, and feed speed are appropriate, and adjust them in time to improve the sorting effect.

5. The equipment is noisy: Check whether the internal parts of the equipment are worn or loose, replace the worn parts or tighten the loose parts.

6. Equipment vibration: Check whether the bracket and foundation are stable, and reinforce the unstable parts.

C. Maintenance and care of flat magnetic separators

During the use of flat magnetic separators, correct maintenance and care are the key to ensure their long-term stable operation and extend their service life. The following will introduce in detail the maintenance and care measures that should be carried out during the use of flat magnetic separators.

1. Regular cleaning

During the use of flat magnetic separators, due to different working environments and materials, it is easy to generate dust and impurities. Therefore, it is necessary to clean the flat magnetic separator regularly. When cleaning, use a soft cloth or brush to gently wipe the surface of the equipment to avoid scratching the equipment with sharp tools. At the same time, during the cleaning process, attention should be paid to checking whether the various parts of the equipment are loose or damaged, and if there are any problems, they should be dealt with in time.

2. Check the magnetic system

The magnetic system of the flat magnetic separator is its core component and directly affects the mineral processing effect. Therefore, it is very important to check the condition of the magnetic system regularly. During the inspection, attention should be paid to whether the magnetic block is detached, damaged or demagnetized, and whether there are foreign objects adsorbed around the magnetic system. If problems are found, the magnetic block should be cleaned or replaced in time to ensure the magnetic separation effect.

3. Check the conveyor belt

The conveyor belt is an important part of the flat magnetic separator, responsible for conveying materials to the magnetic separation area. Therefore, it is necessary to check the wear and deviation of the conveyor belt. If the conveyor belt is found to be severely worn or deviated, it should be adjusted or replaced in time. At the same time, when replacing the conveyor belt, attention should be paid to selecting a conveyor belt that matches the equipment model to ensure the normal operation of the equipment.

4. Lubrication and maintenance

During the use of the flat magnetic separator, the friction between the components will cause wear. In order to reduce wear and improve equipment performance, the equipment should be lubricated and maintained regularly. Appropriate lubricating oil should be selected for lubrication and maintenance, and refilled according to the requirements of the equipment manual. At the same time, attention should be paid to checking the oil level and oil quality to ensure that the oil level is within the normal range and the oil is clean and free of impurities.

5. Electrical system inspection

The electrical system of the flat magnetic separator is the guarantee of its normal operation. Therefore, it is necessary to regularly check whether the wiring of the electrical system is firm, whether the motor is operating normally, and whether the control components are sensitive. If problems are found, they should be handled in time to avoid electrical failures affecting the normal operation of the equipment.

6. Maintenance and maintenance records

In order to ensure that the maintenance and maintenance of the flat magnetic separator are effectively implemented, it is recommended to establish a maintenance and maintenance record system. Each time maintenance and maintenance is performed, detailed records of maintenance content, time, personnel and other information should be recorded. This not only tracks the maintenance history of the equipment, but also provides a reference for regular inspection and troubleshooting of the equipment.

PS: The maintenance and care of the flat magnetic separator during use is crucial. Regular cleaning, inspection of the magnetic system, inspection of the conveyor belt, lubrication maintenance, electrical system inspection, and establishment of maintenance and care records can ensure the long-term stable operation of the equipment and extend its service life. At the same time, these measures can also improve the equipment's mineral processing efficiency, reduce the failure rate, and create greater economic benefits for the company.
